The results of theoretical efficiency investigation of metallized film capacitor electrodes segmentation patterns are presented in this article. The aim of present investigation was the most ef-fective patterns configuration determination using by numerical simulation method. The experimental investigation method of metallized film capacitor electrodes electrodynamic destruction was devel-oped to reach the needed scope. This method differs from the known methods by using samples of metallized polymer film with different segmentation patterns instead of real capacitors. Based on ex-perimental results the numerical model of segmented electrodes electrodynamic destruction was de-veloped using by COMSOL Multiphysics software. This numerical model allows to investigate differ-ent segmentation pattern’s efficiency during self-healing process (recovery of operating ability after dielectric breakdown) and to determine metallization’s electrical parameters without experimental in-vestigations. Existing and novel types of segmented electrodes for metallized film capacitors were in-vestigated. The dependence of electrodynamic destruction energy, i.e. energy needed to breakdown channel isolating, versus destruction time was used as a criterion of segmentation pattern efficiency. Advantages and disadvantages of investigated electrodes segmentation types were determined. The most important result is the best pattern configuration determination. It was found that bridge-diamond segmentation is the most effective patterns configuration for metallized film capacitor’s application. The significance of the obtained results is practical application in capacitor’s manufacturing ability. The developed numerical model and investigation results can be used in design of new metallized film capacitors types with high specific characteristics. |
